NAIL-TRIMMER.

SPECIFICATION fOIming part Of Letters Patent N0. 794,234, dated July 11,1905.

Application filed April 6, 1903. Serial No. 151,275.

To all whom it may concern:

Be it known that I, HENRY LA (Laws, of Auburn, in the county of Cayugaand State of New York, have invented a certain new and usefulNail-Trimmer, of which the following is a specification.

My invention has for its object the production of a nail-trimmer whichis particularly simple in construction and highly durable and effectivein use; and to this end it consists in the combinations and deviceshereinafter fully set forth, and pointed out in the claims.

In describing this invention reference is had to the accompanyingdrawings, forming part of this specification, in which like charactersdesignate corresponding parts in all the views.

Figures 1, 2, 3, and 4 are respectively top plan, longitudinal sectionalview, end View, and isometric view of a preferable embodiment of myinvention, the nail-support and the locking member being shown indifferent positions in full and dotted lines in Figs. 1 and 2. Fig. 5 isa sectional view of a modified construction of knife for my invention.

1 and 2 are respectively the nail-support and knife of my nail-trimmer.The part 1 is generallyformed with side walls 8, arranged atsubstantially right angles with the main portion of said part 1, and isprovided at its front end with an opening 4:, a convex upper face 5, ofsoft metal, beneath and in front of the opening 4 for engaging the undersurface of the nail, and an end face 6 for engaging the finger or toeand regulating the cutting of the nail.

1n the preferable construction of my nailtrimmer the rear end of theknife 2 is arranged beneath the like end of the nail-support 1 and isextended rearwardly beyond said part 1, and the front end of the knife 2is formed of less width than the contiguous main portion thereof and isprovided with upward, forward, and downward extensions 7 8 9, theforward extension 8 being arranged in the opening 4 and having dependingcars 10, pivoted to the side walls 3, and the downward extension 9,terminating in a concave cutting edge 11, of hard metal, cooperatingwith the face 5 for cutting the nail. The advance surface of the knife2, terminating in the edge 11, and also the face 6 of the nail-supportare extended rearwardly from their opposite ends, as shown in Fig. 1,for facilitating cutting of the nail rounding. The front end of theknife2 is usually also formed with a lengthwise corrugation 12 for stiffeningsaid end and with a notch 13 in the upper face of the forward extension8. Although the knife 2 is preferably composed of a single piece ofsteel, it will be obvious that the same may consist of a main body 14and a detachable blade 15, as illustrated in Fig. 5.

16 is a spring for moving the support 1 relatively to the knife 2, and17 is a member for locking the support 1 against the action of thespring 16. As generally constructed the intermediate portion 18 of thespring 16 bears against the upper face of the intermediate part of theknife 2, and the ends of said spring are arranged between the side walls3 and provided with lateral extensions 19, fixed to said side walls. Byconstructing the spring of a single piece of spring-wire to provide anintermediate portion and approximately parallel side arms theright-angular terminals or extensions 19 can be readily sprung into theopenings 19 in the side walls of the member 1. This arrangement willinsure the proper disposition of the spring, permitting the spring to beeasily attached and detached and insuring the same against accidentaldisplacement when in its operative position. The locking member 17 isprovided with a depressed rear 1 end to the knife 2 at the rear of thesupport 1. Its intermediate portion detachably engages the upper face ofthe support 1, and its front end is formed with a point 20, detachablyarranged in the notch 13. The under face of the member 17 is usuallyprovided with a roughened surface for filing the nails.

By reference to Fig. 1 it will be observed that the end face 6 is in theform of a projecting lip extending longitudinally from the member 1, andthe surface for engaging the finger or toe is provided with stop means,conveniently illustrated as being the ends of the side walls of themember 1. The rigid upstanding edges of these side walls will insure auniform cut being made in each instance.

The construction and operation of my nailtrimmer will now be readilyunderstood upon reference to the foregoing description and theaccompanying drawings, and it will be apparent to those skilled in theart that more or less change may be made therein without departing fromthe spirit of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A nail-trimmer comprising a member having one end provided with anopening and with a supporting-face for the nail, and a second memberconsisting of a strip having one end arranged beneath the other end ofthe first member and its opposite end extended upwardly and forwardly,and downwardly, said opposite end being extended through said opening ofthe first member, and the downwardly-extended portion terminating in acutting edge for cooperating with the supportingface, one of saidmembers being movable relatively to the other, substantially as and forthe purpose specified.

2. A nail-trimmer comprising a member having one end provided with anopening and with a supporting-face for the nail, and a secand memberconsisting of a strip having one end arranged beneath the other end ofthe first member and its opposite end extended upwardly and forwardly,and downwardly, said opposite end having a substantially lengthwisecorrugation and being extended through said opening in the first memberand the downwardly-extended portion terminating in a cutting edge forcooperating with the supporting-face, one of said members being movablerelatively to the other, substantially as and for the purpose described.

3. A nail-trimmer comprising a pair of members provided respectivelywith a supporting-face and a cutting edge cooperating with each other,one of the members having one end arranged below the like end of theother member and its other end arranged above the opposite end of saidother member, and one of said members being movable relatively to theother, a spring having its intermediate portion engaged with one of saidmembers and its ends formed with lateral extensions fixed to the othermember, and means for locking the relatively movable member against theaction of the spring, substantially as and for the purpose set forth.
